Professional Applications & Engineering Value
This 18-8 stainless steel set screw is engineered to address critical challenges in precision machinery, automotive assemblies, and heavy-duty equipment. The UNC coarse thread and Class 3A fit ensure rapid installation and superior resistance to loosening under dynamic loads, while the cone point digs securely into shafts and collars to prevent axial movement. Its headless design with a hex drive allows for compact installations in tight spaces, making it ideal for securing gears, pulleys, and couplings. The combination of stainless steel material and Rockwell B80 hardness provides excellent durability against corrosion and wear, reducing maintenance needs in demanding industrial environments.
Specification Summary & Compliance
This set screw adheres to ASME B18.3 specifications, with precise UNC coarse threading (5/16"-18) and Class 3A thread fit for high accuracy. It features a right-hand thread direction, 1/4" length, and 118° cone point angle for optimal performance. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and suitability for global industrial applications.
